It occurred to me that most of the work I do on my shiny dual core i7 ultrabook is using VIM, Python, ssh, and other command-line tools. So why do I need a fast CPU and fancy graphics?

When the Raspberry Pi B+ was released, I knew I had to try this. I ordered one, installed Raspbian and all the stuff I needed, and took it to work.

I hooked up an external monitor, keyboard, and mouse. Then I sneaked a LAN cable into the WiFi hotspot and set to work.

I decided to forgo X entirely. As I mentioned, I use mostly terminal applications, and alternatives for the few GUI apps I use are readily available.

After a week, I can say it worked surprisingly well. I could pretty much do my job as usual. Most applications never used much CPU or memory. And even while compiling Python 3.4 from source, my terminal stayed snappy.

The only mayor problem is browsing the web. Elinks is pretty good, and most things that do not use JS are usable, but it’s not ideal. At times I had to startx and fire up Midori. It’s so much slower and resource hungry than elinks though.

On the upside, RFC’s look pretty much unchanged. Still dry and boring.

The one application that makes this work is tmux. Without tmux there is no way this would ever work. Tmux is my tiling window manager. Everything I do, I do it in tmux.

The best part is that you can startx, open a terminal, run tmux attach and continue working alongside the sluggish GUI apps. You could even walk over to a colleague, ssh to your machine and work there.

I use fbterm as my terminal emulator. This allows you to use your favourite monospaced font in a framebuffer. I use Zsh for my shell. I can highly recommend the .zshrc from grml.

I recommend that you enable overclocking and adjust the memory split to 16MB to give you all the resources you can get. However, this is mostly for web browsing, on the console you don’t notice the difference.

During the weekend before the experiment, I had a lot of fun setting up all the tools I need and more.

I set up alpine for email and weechat for IRC, but also youtube-dl and mplayer for playing videos in a framebuffer.

I did experiment with netsurf. A graphical browser in a framebuffer. The problem is that there is still no JS, and there is no way to quit it. So for times that elinks is not enough, you really want proper webkit.

In the case you want to try this, here are some essential keyboard shortcuts I learned in te past few days.

Tmux commands are all prefixed with ctrl+b. Put set -g mode-keys vi in ~/.tmux.conf for copying to work.

Weechat is mostly controlled by IRC commands I used anyway such as /join and /quit. To switch buffers you press alt+0-9. It really helps to install the buffers.pl script so you can see a numbered list of them.
